ICE-PICK.

SPECIFICATION forming part of Letters Patent No. 441,333, dated November25, 1890;

Application filed September 19, 1890. Serial No. 365,475. (No model.)

To CLZZ whom it may concern:

Be it known that I, ALBERT B. SCHOFIELD, of Brooklyn, in the oounty ofKings and State of New York, have invented a new and useful Improvementin Ice-Picks, of which the following is a specification.

My invention relates to an improvement in ice-picks in which a slidingweight, which acts as a hammer, is arranged to strike an abutment uponthe shank of the pick to embed the cutting edge or point into the ice.

The object is to provide a device of this character in which the shankshall be light and stiff, and in which the parts may be assembled in asimple and effective manner, so as to split the pieces of ice of variousdimensions and thicknesses in the direction desired.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure 1 is a view of the pick in sideelevation. Fig. 2 is a transverse section through line oc 00 of Fig. 1.Fig. 3 is a partial view, in side elevation, showing the shank providedwith points instead of blades. Fig. 4 is a partial view showing theshank provided with a single blade, instead of two separate blades. Fig.5 represents the weight or hammer provided with perforations, instead ofgrooves, for the reception of the parts of the shank; and Fig. 6represents the abutment formed in two half-sections and secured upon theshank.

A A represent the two parts, rods, or bars of the shank. It ispreferably formed of a single piece of wire bent in U- shaped form, asshown, the parts A and A extending parallel with each other and spacedapart. The bight Cb at the upper end of the shank forms a convenientmeans for suspending the pick upon a hook or nail when not in use. Inthe form shown in Fig. 1 the free ends of the parts A and A areflattened into cuttingblades a, the blades being preferably arranged inalignment edgewise. Above the blades a the parts A and A are united byan abutment B, which forms at the same time a seat for the impact of thehammer or weight, and also a binder for holding the two parts A A inposition relatively to each other. The abntment B may be formed in onepiece, as shown in Fig. 1, and provided with perforations b therethroughfor the reception of the parts A A, or it may be formed in twohalf-sections B, as represented in Fig. 6, the

two half-sections being provided with rccesses b, which,when thesections are united, serve to surround snugly the parts A A. Theabutment B is held securely against dis placement toward the cuttingblades a either by the spreading of the parts of the shank in proximityto its lower edge, as shown at a or it might be riveted to the shank orotherwise secured in any well-known or approved manner.

The weight C is provided at its opposite sides with grooves o, adaptedto receive the adjacent sides of the parts A A of the shank, and whenadjusted is securely held in a free vertically-sliding movement betweensaid parts of the shank. Instead, however, of being provided withgrooves, as shown in Figs. 1 and 2, the said weight may be provided withperforations, as represented in dotted lines at o, Fig. 5.

In the place of the blades a the free ends of the parts A A may bepointed, as shown at af, Fig. 3, or a single blade a may be secured tothe free ends of the shank, as represented in Fig. 4.

The parts may be assembled by first forming the shank and then, beforethe cutting points or blades are formed, the weight C may be slid intoits position and the abutment B driven over the free ends of the shankinto its position. The free ends of the shank may then be spread orpointed, or a blade, as a may be fixed thereto. Of course where theabutment is formed in two half-sections, as shown at B, it may be placedin position after the points or blades have been provided.

By the above construction I secure ashank which is stiff and at the sametime light, while its formation is such as to readily in dicate to thetouch the direction in which it should be placed in order to split iceas de sired. It may also be held firmly and truly in the hand without1iability of turning, while the points or blades at'the free ends of theparts beingseparated from each other insure a separation of the ice inthe line of direction in which they engage it. The formation of theshank in two parts further ICO admits of securing the weight in slidingadjustment, as shown in Fig. 1, simply by grooves along its sides,instead of the more expensive structure shown'in Fig. 5.

W'hat I claim as my invention is 1. An ice-pick the shank of whichconsists of a pair of bars 01 r0ds having their free ends sharpened, anabntment seeured to the said rods or bars, and a weight free to slide upand down between the said r0ds or bars, substantially as set f0rth.

2. An ice-pick the shank of which consists of a rod 01' bar bent intoU-shaped form and having its free ends fiattened into cutters, anabntment secured to the branches of the shank, and a weight havinggrooves in ALBERT 13. SOHOFIELD.
